Even if I make 400K a year, my wife is working, if we didn’t live in the West, it’d be a different argument.
Having a homemaker wife is a fantasy shown on television. The harsh reality is that most of us will not be rich but middle class and by having one parent stay at home, you’re essentially reducing the amount of money available for the family to utilise.
Even if your wife makes 50K a year, that’s an extra 50K that can be put into an index fund or pay bills or used to send kids to private school.
